Looks like the mayor had better not order the new drapes for the Oval Office just yet:

Compared to Quinnipiac's last national poll in February, Mr. Giuliani fell to 27% from 40% — a huge tumble. Mr. Romney barely budged, going to 8% from 7%. Mr. McCain also barely budged, going to 19% from 18%. And Mr. Thompson burst onto the scene, coming in at 14%, having not been included in the last poll (and, as usual, stealing third place from Mr. Romney, despite not having lifted a finger).

And:

While Mr. McCain's favorable-unfavorable ratings have deteriorated slightly with the public at large, he's gained among white Evangelicals while Mr. Giuliani has seen an erosion. In February, Mr. McCain's fav-unfav with white Evangelicals was 53%-24%; now, it's 58%-15%. Among the same group, Mr. Giuliani went from 62%-16% in February to 57%-19% today.

These aren't huge jumps on either side. But they are evidence that Mr. Giuliani's liberal social views are catching up with him, while Mr. McCain is having some success reminding social conservatives that, though he's had some spats with the religious right, his views aren't that far out of the Republican mainstream.
